Honestly, use any good body butter or bio oil to stop the dryness, but stretch marks are mostly genetic. They will fade on their own over time, so don't stress about them.
Regular coconut oil or aloe vera gel keeps the skin very soft and hydrated. But if you have severe, intense itching all over your body, please check with your gynac immediately.
I used simple olive oil but was very careful with what creams I applied because of my sensitive skin. Always ask your doctor before using any medicated stretch mark creams.
Gentle massage with warm almond oil helps a lot with the stretchiness. My marks have faded so much now during my breastfeeding journey, so give it some time.
I had such bad vomiting that applying heavy-smelling creams made me nauseous. I stuck to odorless virgin coconut oil right after my bath, which worked wonders and didn't trigger my sickness.
